MACHINE FOR UNlTlNG SOLES AND UPPERS.

EPEQIFICATIQN forming part of Letters Patent No. 319,127, dated June 2, 1885.

Application filed September 29, 1864. (No model.)

To all whom it may concern.-

7 Be it known that we, SrrILLnLiN W. Romn- SON and ORLANDO E. Lnwrs, both of Columbus, county of Franklin,and State of Ohio, have invented an Improvement in Machines for Uniting Soles and Uppers, of which the following description, in connect-ion with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

In the manufactureof boots and shoes wherein the sole-fasteners are automatically driven through the sole and upper it is customary, especially when metallic fasteners have been used, to last the boot or shoe on a last, then withdraw the last preparatory to placing the boot or shoe upon a horn for the reception of the sole-fasteners, and after the fasteners have been inserted or driven the. boot or shoe removed from the horn has been again placed upon alast to be finished. Desiring to obviate the expense attendant upon removing the last from the boot or shoe between the lasting operation apd that of driving or inserting the sole-fastenings, and also to finish or tree the shoe on the last upon which it was lasted, we have produced a hollow metal shell-like last upon which the boot or shoe may be lasted, and thereafter by the removal of the last-block the hollow last may be applied to the horn of a nailing-machine, the lastbeing moved about on the surface of the horn while the sole-fastenings are being inserted. In the manufacture of boots and shoes by machinery having a horn either the tip of the horn or the nose is always brought to a definite position, while the other yields to adapt itself to the thickness'of the stock being worked upon, and the member which is thus variable as to its position usually automatically controls thelength of the fastener to be driven, especially if a wire is used. In this instance we have shown our improvement applied to a horn the top of which is supposed to always stand at a defined level while the fastener is being inserted, the horn being, for instance, such as represented in United States Patent No. 297,718, dated April 29, 1884, wherein the horn always occupies the same position while the fastener is being inserted, and wherein the nose rises and falls to adjust itself to the thickness of the stock and to vary the length of the fastening.

The hollow or shell-like lastupon which the boot or shoe is lasted, and which last is applied to the horn while the shoe is upon it, is so chambered as to permit the horn to pass into the last and have its tip presented with reference to the sole and upper just as when the boot or shoe is applied directly to the last, and to prevent the last from interfering with the production of fasteners of the proper length we havefound it essential to make that partof the last which comes directly in contact with the tip of the horn of uniform thickness, so that the bottom of the last, supported by the horn, will always come to a certain definite height, just as when the horn was used alone. The ends of the fasteners being inserted, meet the bottom of the metal last, the horn merely supporting the last.-

Figure 1, in side elevation and partial section, represents a sufficient portion of a machine for unitingsoles to uppers to enable our invention to be understood; Fig. 2, a partial view of the last and its block, the latter being held in place. the last, partially broken out to show the devices fcr retaining the block in position with relation to the body of the last.

The rotating horn H is substantially the same as in other nailing-machines heretofore employed in boot and shoe work-as, for instance, in United States Patent No. 297,718.

The body A of the last is made to represent a thin last-shaped shell, the bottom I) of which, along each edge of the last from heel to toe and about the toe and heel, as shown by section and dotted lines, Fig. 1, is of substantially uniform thickness, so as to always present in all positions of the last upon the tip of the horn, and while the last is moved longitudinally and rotated on the said tip, the same amount or thickness of material. The block a of the last, provided with the usual prong or catch, 0, and with projections 0 to pass into the body of the last to assist in holding the block securely in place thereon, is made longer than heretofore in metal lasts, so that ample room is leftfor the reception and rotation of the horn when the block is removed from the last, the block being retained chiefly by the block-locking device d, (shown as a latch pivoted at d.) The upper and sole Fig. 3 is a side elevation of 5 of the boot or shoe to be made having been lasted upon the last composed of the body A and block a, and the outer sole having been tacked upon the lasted boot or shoe, the block cis withdrawn and the last-body with the shoe or boot yet upon it is placed on the horn H, the tip of the horn acting as a support for the inner side of the bottom of the last as the latter is moved longitudinally on the horn. The fasteners having been inserted, the last, with the shoe or boot yet on it,.is removed from the horn, the block 0 is again inserted in the boot or shoe, and the upper and sole are thereafter finished in the usual manner, after which the last is placed upon the pin of a jack, the last having a hole, 3, made therein for such purpose, and the heel is applied in usual manner. By not removing from the boot or shoe the last upon which it was lasted until after the sole and upper have been permanently secured and the sole finished, the boot or shoe is kept in its original shape instead of being stretched out of shape, as is apt to be the case when the boot or shoe in the process of its manufacture is applied to first one and then another last and is entirely removed from a last when the sole and upper are being united in a railway-machine while held by hand. The operator will move the last and shoe on the horn, and will partially rotate the horn, just as he formerly moved the lasted shoe after removing thelast. The last is entirely unobstructed at the inner side of .ing entirely around the toe portion of the last,

its bottom from edge to edge, so that the last may be freely moved on the horn.

I claim 1. The hollow metallic shell-like last cut away substantially as shown and described, whereby the top of the horn may have a bear- 0 substantially as described.

2. The hollow metallic shell-like last having the chamber for the reception of the horn, and provided with the hole 3 and the block, to operate substantially as described.

3. The hollow metallic shell-like last having its bottom of uniform thickness where the same rests upon the tip of the horn, substantially as and for the purposedescribed.

4. The combination, with a horn, of the hollow metallic shell-like last cut away to permit the entrance of the tip of the horninto the toe of the last opposite the point at which the sole-fasteners are to be'inserted, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
